The situation today in most operating theaters is characterized by a large number of highly specialized but
isolated surgical-assist systems. Integration of these systems into a complete solution is the key to maximize
their usefulness and cost-effectiveness through optimization of the data flow and reuse of existing hardware. Goal
of the integration is the design of a distributed assist system by connecting multiple independent components
using standard protocols for communication and data exchange. Required surgical functionalities are created by
combining the appropriate components.
Such a distributed assist system induces fundamental changes in the nature of the data flow among individual
components. Today, components tend to exchange more-or-less independent and self-contained units of information
which they process once the complete data set has arrived. However, with distributed functionalities and
tighter integration necessary to complete a surgical process, increased continuous data transfer and processing
will be required. To handle this type of data transmission, the system will have to support streaming of continuous
data.
We present a general framework for the integration of data streaming into the Digital Operating Room. The
approach presented provides a two level system in which the management and supervision of the data producing
and consuming devices is independent of the actual mechanisms used to transmit the data. This approach allows
the use of infrastructure and transmission technologies specially adapted to the specific needs of the streamed
data.
